Something deep within you seems ready to come to terms with the abuse he inflicted on you as a child. You can forgive him without restarting contact, but it seems like you desire contact at this point. Do you have a support system in place in case contact stirs up strong and unexpected emotions? If not, you might want to consider finding a trusted friend or counselor who could be supportive. You could also consider writing out what it is you hope to accomplish through contact, such as forgiving him in person, wanting to be able to ask him why he did it, wanting to hear an admission and apology? Or do you want to let him know how his actions did hurt you? Say I love you?
There are no easy answers to your question and only you can figure out what it is that you're truly looking for. Forgiveness, if you're ready can be a very healing and powerful process that helps you move on and release the hurt that's been buried inside you.
As I already said it can be achieved with or without direct contact.
On the other hand, if you're ready for contact and know what your expectations are and are prepared should they not be met, attempting contact can also be a helpful thing.
My brother, who was an alcoholic, sexually molested his 5 year old daughter and thereafter was only allowed supervised visits when his wife divorced him due to her discovery of the sexual abuse. As a young teen, his daughter wanted no contact at all with her Dad, but when she was 18 her father was in the hospital dying from cirrhosis of the liver, and she chose to visit him every day during the last few days of his life (he was only 44). The reunion was bittersweet due to the circumstances, but I know it was emotionally healing for both of them. I will never forget the way she held his hand and stroked his forehead during his last few (comatose) hours. Tears streamed down her cheeks and there was such tenderness and love on her face that a stranger witnessing them together would never have known there had ever been anything but love between them. This was 10 years ago and she's doing well now with 2 small children of her own.
